New York: Defending champion Rafael Nadal and world number one Novak Djokovic will meet in the US Open final on a Monday for a second straight year, but things could not be any different than they were 12 months ago.

In 2010, Nadal was almost unbeatable, a player at the peak of his powers. The Spaniard had just won the French Open and Wimbledon titles and reached the final at Flushing Meadows without dropping a set.

Though Nadal beats Djokovic in four sets in the final last year, the Serb holds a 5-0 record in the last five finals played between the two.

Rafael Nadal booked a US Open title showdown against Novak Djokovic on Saturday with a bruising 6-4, 6-2, 3-6, 6-2 win over British fourth seed Andy Murray.

Nadal, the second seed, will be playing in his 14th Grand Slam final on Monday in what will be a repeat of last year's final where he became the youngest man to complete a career Grand Slam.

Nadal made sure he could get the majority of support in the final by taking time to remember the victims of the September 11 attacks, ahead of the 10th anniversary on Sunday.

In the other semifinal, World number one Novak Djokovic saved two match points as he climbed out of a two-set hole to beat five-time champion Roger Federer on Saturday to reach the US Open final.

The top-seeded Serb, who had also saved two match points en route to a semifinal win over Federer at Flushing Meadows last year, triumphed 6-7 (7/9), 4-6, 6-3, 6-2, 7-5.

He avenged his loss at the hands of the Swiss legend in the French Open semifinals, a defeat which ended his 43-match winning run.

Federer had appeared poised for victory after breaking Djokovic to love for a 5-3 lead in the fifth set -- Djokovic's untimely double fault giving Federer triple break point in that game.

Defeat for Murray, who joined an elite band of seven players to have reached the semifinals of all four grand slams in a calendar year, means that Britain's long wait for a first major winner since Fred Perry in 1936 goes on.
